@Sarah, I already got the kit and it is layered psd files. Each color is on it's each layer. You can just use the papers you want and create a clipping mask. I believe if you merge it will keep the button characteristics (haven't used it yet). I also have an action, Cover It, by Wendyzine that will cover it and then it keeps the characteristics of the template, ie shine with one simple click. It really works for both PSE and PS. I used it in PS CS6 and it will cover any element not just buttons! Cost $3.99
